Abstract: Provided are picture encoding and decoding methods and apparatuses, and a picture encoding and decoding system. The picture encoding method includes: determining an adjustment factor according to pixel sampling values of a video picture; converting the video picture according to the adjustment factor, and encoding the converted video picture; and writing the adjustment factor into a bitstream obtained by encoding the converted video picture.

Abstract: Disclosed are a bitstream alignment and synchronous processing method, transmitting terminal, receiving terminal and communication system. The method includes: configuring, when multiple bitstreams are required to be aligned, by a transmitting terminal, alignment auxiliary information in the multiple bitstreams so as to store the same or transmit the same to a receiving terminal; and acquiring, by the receiving terminal, the multiple bitstreams, and synchronizing each of the bitstreams of a different standard according to the alignment auxiliary information carried in each of the bitstreams.

Abstract: Disclosed are an image encoding and decoding method, image processing device, and computer storage medium, comprising: entropy-encoding a plurality of replication parameters of a current encoding block according to their order after adjustment, to generate a video code stream comprising information of the plurality of replication parameters; said plurality of replication parameters comprising one or more types of replication parameter components. Parsing the video code stream, comprising the information of the plurality of replication parameters, of a decoding block; entropy-decoding said plurality of replication parameters to obtain binary code of said plurality of replication parameters; adjusting said binary code to obtain the values of said plurality of replication parameters; said plurality of replication parameters comprising one or more types of replication parameter components.
